General Description
A pale yellow oily liquid with an odor of onions. Highly toxic by inhalation and skin absorption. Strongly irritates skin and mucous membranes. Density 1.265 g / cm3. Insoluble in water and soluble in alcohol. Noncombustible.
Air & Water Reactions
Insoluble in water. Slowly decomposed in water.
Reactivity Profile
PHENYL ISOCYANIDE DICHLORIDE may be incompatible with water, strong oxidizing agents, alcohols. Sealed containers held at room temperature may explode, due to slow decomposition that builds up pressure. This situation is more dangerous with heat. May react vigorously or explosively with diisopropyl ether or other ethers in the presence of trace amounts of metal salts [J. Haz. Mat., 1981, 4, 291].
Health Hazard
Highly toxic, may be fatal if inhaled, swallowed or absorbed through skin. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
Fire Hazard
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Containers may explode when heated. Runoff may pollute waterways.
Safety Profile
A poison by inhalation. When heated to decomposition it emits toxic vapors of NOx and Cl
Potential Exposure
Phenylcarbylamine is used in organic synthesis; making other chemicals. A laboratory chemical and a former battlefield gas
Shipping
UN1672 Phenylcarbylamine chloride, Hazard class: 6.1; Labels: 6.1-Poison Inhalation Hazard; Inhalation Hazard Zone B. PGI.
Incompatibilities
Reacts slowly with water releasing hydrogen chloride. Sealed containers stored at room temperature may explode, due to slow decomposition that builds up pressure. Heat increases the danger of explosion . Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. alcohols.
Waste Disposal
Use a licensed professional waste disposal service to dispose of this material. Dissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal, state, and local environmental regulations must be observed. It is not appropriate to dispose of expired or waste product such as lab chemicals by flushing them down the toilet or discarding them to the trash. Larger quantities shall carefully take into consideration applicable EPA, and FDA regulations. If possible return the lab chemicals to the manufacturer for proper disposal being careful to properly label and securely package the material. Alternatively, the waste lab chemicals shall be labeled, securely packaged and transported by a state licensed medical waste contractor to dispose by burial in a licensed hazardous or toxic waste landfill or incinerator. All federal, state, and local environmental regulations must be observed.
Check Digit Verification of cas no
The CAS Registry Mumber 622-44-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,2 and 2 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 622-44:
(5*6)+(4*2)+(3*2)+(2*4)+(1*4)=56
56 % 10 = 6
So 622-44-6 is a valid CAS Registry Number.

Synthesis and antimicrobial activity of 3-aryl-2,6-diphenylimino-4-S-hcpta- O-benzoyl-lactosyl-2,3-dihydro-1,3,5-thiadiazine hydrochlorides

A new series 3-aryl-2,6-diphenylimino-4-S-hepta-O-benzoyl-lactosyl-2,3- dihydro-1,3,5-thiadiazine hydrochlorides have been synthesized by the interaction of S-hepta-O-benzoyl-lactosyl-1,5-disubstituted-2,4-isodithiobiurets and phenyl isocyanodichloride. The newly synthesized compounds have been characterised by analytical and IR, 1H NMR and Mass spectral studies. These newly synthesized thiolactosides are also tested for antibacterial and antifungal activity.
Lifetimes of imidinium ions in aqueous solution
Dalby, Kevin N.,Jencks, William P.
, p. 7271 - 7280 (2007/10/03)
Imidinium ions, ArN=CNR2+, were generated in aqueous solution from the solvolysis of fluoro and chloro formamidines at pH 9.3 and 25°C. Rate constants for the hydration of five imidinium ions were determined from a kinetic analysis of their trapping by thiolacetate anion, CH3COS-, in the presence of a pool of competing fluoride anion, and a rate constant of k(AcS)- = 5 x 109 M-1 S-1 for diffusion-controlled trapping of the carbocations with thiolacetate anion. The rate constants, k(s), for hydration of the imidinium ions, XArN=CNC4H8O+ are 3.6 x 105, 5.8 x 105, 1.5 x 106, 1.6 x 106, and 1.8 x 106 s-1 for X = H, 4-Cl, 3-CN, 4-CN, and 3-NO2, respectively. In a similar experiment a rate constant of k(s) = 3.3 x 107 s-1 was obtained for hydration of the imidinium ion 4-NO2-ArN=CNCH3(OCH3)+, by using azide anion to trap the cation and a rate constant of k(az) = 5 x 109 M-1 s-1 for diffusion-controlled trapping of the imidinium ion with azide ion. The partitioning rate constant ratio k(AcS)-/k(s) for 4-ClArN=CNC4H8O+ decreases by approximately 6-fold in 45% v/v glycerol/water in contrast to k(az)/k(s), which remains almost constant, showing that thiolacetate, but not azide anion, combines with the imidinium ion at a diffusion-limited rate. The reactivity of the imidinium ions deviate from behavior predicted by the N+ scale in a manner that may be explained by a difference in the selectivity of the cation when compared to the more stable N+ carbocations.
